Mefast 100 Suspension contains Mefenamic Acid 100 mg per 5 ml, a non-steroidal anti-inflammatory drug (NSAID) used primarily for the relief of mild to moderate pain and inflammation. It is indicated for conditions such as dysmenorrhea, musculoskeletal pain, dental pain, and postoperative pain. Mefenamic Acid exerts its effect by inhibiting cyclooxygenase enzymes (COX-1 and COX-2), leading to decreased synthesis of prostaglandins, which are mediators of inflammation and pain. This suspension formulation allows for ease of administration, particularly in pediatric and geriatric populations who may have difficulty swallowing tablets. The recommended dosage should be adhered to strictly to minimize adverse effects, which may include gastrointestinal disturbances such as nausea, vomiting, dyspepsia, and, rarely, more serious events like gastrointestinal bleeding or renal impairment. Mefast 100 Suspension should be used with caution in patients with a history of peptic ulcer disease, renal or hepatic dysfunction, and cardiovascular disorders. It is contraindicated in individuals with known hypersensitivity to mefenamic acid or other NSAIDs. Patients are advised to take the medication with food to reduce gastrointestinal irritation. Consultation with a healthcare professional is essential before initiating therapy to ensure appropriate use and monitoring.
